Function gpu_alloc_ash::device_properties

pub unsafe fn device_properties(
    instance: &Instance, 
    version: u32, 
    physical_device: PhysicalDevice
) -> Result<DeviceProperties<'static>, Result>

Returns DeviceProperties from ash’s InstanceLoader for specified PhysicalDevice, required to create GpuAllocator.

Safety

physical_device must be queried from Instance associated with this instance. Even if returned properties’ field buffer_device_address is set to true, feature PhysicalDeviceBufferDeviceAddressFeatures::buffer_derive_address must be enabled explicitly on device creation and extension “VK_KHR_buffer_device_address” for Vulkan prior 1.2. Otherwise the field must be set to false before passing to GpuAllocator::new.
